titleOfInvention | Method and device for determinations hydrogen peroxide |
abstract | PURPOSE:To rapidly and simply measure H2O2 in a minute amount of 1ppm or less, by a method wherein, after sample liquid is treated by a treating liquid containing an oxidizer and is deoxidized, a detection is made on oxygen produced through implanting of catalase. CONSTITUTION:A specified amount of a solid sample is placed in a homogenizer, and is equalized by adding treating liquid, obtained resulting from filteration of the treating liquid, is poured into a receptacle 2, N2 gas is led into measuring liquid 2' in the reaction receptacle 2 and in an upper space 2'' of the reaction receptacle 2 through a 4-way cock 7 for switching N2 gas to exhaust all oxygen in the reaction receptacle 2. Then, the switch cock 7 is switched to a flow path shown in a dashed line to lead N2 gas only to the upper space 2'' in the reaction receptacle 2. A catalase solution, previously deoxidizing, is measured into a syringe 15 from a storage tank 14, and the catalase solution is implanted to measuring liquid through insertion of the syringe 15 into a cover. The implatation detects dissolved oxygen, generated in the measuring liquid, by means of an oxygen electrode 1 to find the H2O2 concentration of the measuring liquid. |
